Highbeam/Lowbeam

[JHoffy8]

I just installed a round headlamp on my F... do the round lamps have a highbeam/lowbeam? When I flip the switch it doesnt do anything... is this just the bulb or is it just one setting with these lights?

They do, your bulb must be down a filament. You could also have a wiring problem... When you say doesn't do anything, do you mean the light stays the same or the light goes out? If you're missing a single filament, the light will go out at one of the positions. If the light stays on no matter what position the highbeam switch is in, you've got a wiring problem...
